cortexa5t2

Wed Jul 19, 2017 8:16 pm

hello,
I am working on a project with sama5d3 with linux.
I have downloaded poky qt sdk for cortexa5t2 and cross compiled my code for the sama5d3 environment. the question is if I can cross compile with cortexa5t2 and it will work? or I have to use a cortexa5 sdk?
what is the different between cortexa5 and cortexa5t2?

thanks,

If you don't know what it is, then why try to use it?

For a WAG, one SDK uses the ARM instructtion set, and the other uses Thumb-2?

I have a board with SAMA5D3, and I want to cross compile application for it.
so how do I know which instruction set is used in the board ?

and will code compiled with thumb2 work on linux compiled without the thumb2?

how can I solve the problem?

You would have to know how the system was configured and built.

Again, that would depend on how the system was configured.

What problem? You haven't clearly articulated a problem.
